Lvm auto. LVM(Logical Volume Manager) is a very important concept to Manage and utilize storage devices effectively Let’s understand the concept of LVM through an example where suppose if you have any two traditional storage devices with size 50 GB each and one of the storage device has 5GB free space and another has 10GB. Logical Volume Manager (LVM) plays an important role in the Linux operating system by improving the availability, disk I/O, performance and capability of disk management LVM is a widely used technique that is extremely flexible for disk management. One good thing about systemconfiglvm is that it won't allow you to go ahead if the new partition size is smaller than all your existing data combined (I've just tried this and seen for myself) References HowTo Geek tutorial (this is the origin of the images) Red Hat's complete guide for the program.

Logical Volumes (LV) are the final storage unit in the standard LVM architecture These units are created from the volume group, which is made up of physical volumes (PV) If you have been following along in the series, you will have initialized your physical volumes and combined them into a volume group (VG). A quick check of the LVM docs reveals that pvmove with no arguments (other than the device) moves all the data on the device to free space in the volume group, wherever it can find it It's basically "move this data to anywhere else" as opposed to "move this data to this particular place" which is what we were doing with the previous uses of.

Two LVM logical volumes (LogVol00 and LogVol01) are created from the newly created spanned volume group In the following example, the recommended swap space is automatically calculated and assigned to LogVol01, and the remainder is allocated to the root file system, LogVol00.

LVM Logical Volume manager is a disk management solution that allow administrators to manage disk space more effectively LVM allows us to to add, remove, resizing the size online in the existing volume without taking any downtime.
